Exuding confidence that there will not be hung assembly in Mizoram as the ruling MNF will sweep the polls, Chief Minister Zoramthanga on Tuesday said his party does not have an alliance with the BJP in the state and its support to NDA at the Centre is "issue-based". Asserting that the MNF's efforts to integrate Zo tribes will reap electoral benefits for the party, he said people fleeing from Myanmar, Bangladesh and Manipur feel safe in Mizoram which is ruled by his party.
